SEED SEPARATOR Filed March 8, 1937 darl .3137 e/ l VEN OR' v it ATTORNEY8 Patented Nov. 29, 1938 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to seed separators and has for the primary object the provision of a device of this character which may be successfully employed for separating different kinds of seeds, thereby eliminating the necessity of having to employ a different machine or separator for each kind of seed, which is now the practice and which requires a large financial outlay besides requiring an excessive amount of space for the accommodation of such machines or separators.

Another object of the invention is the provision of a machine of the above stated character which is so constructed as to permit separator units designed for different kinds of seeds to be easily and quickly adapted to or removed from the machine, so that one machine can be readily converted for use in separating different kinds of seeds.

With these and other objects in view, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is an end View partly in section illustrating a seed separator constructed in accordance with my invention.

Figure 2 is a vertical sectional View illustrating the means of removably mounting a separator unit on the machine.

Figure 3 is a fragmentary vertical sectional view illustrating one means for removably securing the separator unit on the machine.

Figure 4 is a fragmentary vertical sectional view illustrating one of the ends of the separator unit.

Referring in detail to the drawing, the numeral 1 indicates a frame of a seed separator including supporting rollers 2 on which is mounted for rotation a separator unit support 3 including a cylinder 4 equipped at its ends with bearing sleeves 5 grooved to receive the rollers 2 and each includes a flange 6 provided with screw threaded apertures to receive stud bolts 1.

During the use of the machine for the purpose of separating the seeds the cylinder 4 is rotated by the rollers 2, the latter being driven in any well known manner and forms no part of the present invention.

Operating within the cylinder 4 is a separator unit 8 which may be of any well known construction and in this instance is in the form of a cylinder having a plurality of sumps 9 in which the seeds collect during the operation of the machine for delivery into a conveyor In. In order that this machine may successfully separate different kinds of seeds it is the primary object to provide separator units designed for the different kinds of seeds and in order that these different separator units may be employed in one machine a removable connecting means is provided between the cylinder 4 and the separator unit and consists of a pair of annular heads ll arranged at each end of the sleeve and each equipped with apertured ears l2 to receive the stud bolts 1 whereby the heads are detachably connected to the cylinder 4. Eachhead also includes a bearing portion l3 in the form of a sleeve, the end of which is beveled to form a seat 14. The ends of the separator units are also beveled to match the seats l4. Thus it will be seen that the heads II will efficientlysupport a separator unit within the cylinder 4 for rotation therewith. By tightening the stud bolts 1 a frictional drive is provided between the heads and the separator unit and as the heads rotate with the cylinder 4 the separator unit is consequently required to rotate with the cylinder 4. Whenever it is desired to change a separator unit it is only necessary to detach theheads from the cylinder 4 and withdraw the separator unit from the cylinder and another separator unit designed for another kind of seed may be readily placed in the cylinder 4 and connected thereto by the heads ll.

With reference to the foregoing and the accompanying drawing it will be seen that a separator of this kind by having separator units for every kind of seed can be at any time easily converted for separating seeds of a selected kind, thereby eliminating the present practice of employing complete separating machines for each kind of seed which materially reduces the cost of seed separation.

Having described the invention, I claim: In a seed separator, a cylinder, bearing sleeves mounted on the cylinder at the ends thereof to contact a supporting means and including flanges having screw threaded openings, a separator cylinder having beveled ends received in the first named cylinder, annular heads having beveled ends to engage the beveled ends of said separator cylinder, flanges formed on the heads and arranged exteriorly of the first named cylinder and paralleling the flanges of said sleeves, and stud bolts extending through the flanges of the heads and threaded in the screw threaded openings of the flanges of said bearing sleeves.
